Definitions

  • the segmented core preferably further includes an annular ring segment on the outward of the moat and preferably located on the periphery of the intermediate segment and having a relative refractive index that is greater than the relative refractive index of the intermediate segment, and a width.
  • D DC ( ⁇ ) is the dispersion of the dispersion compensating fiber at a particular wavelength
  • L DC is the length of the dispersion compensating fiber
  • D ⁇ ) is the dispersion of the transmission fiber at a particular wavelength
  • ⁇ is a particular wavelength in the optical transmission band
  • L ⁇ is the length of the transmission fiber (e.g., a NZDSF).
  • the dispersion compensating (DC) fiber according to the invention described and disclosed herein has a generally segmented structure, as shown in Fig. 1.
  • Each of the segments is described by a refractive index profile having a relative refractive index percent, ⁇ ; , and an outside radius, r..
  • the subscript i for r and ⁇ refers to a particular segment.
  • the segments are numbered ⁇ through r beginning with the innermost segment that includes the fiber's longitudinal axis center line.
  • a clad layer having a refractive index of n surrounds the DC fiber.
  • Fig. 1 A clad layer having a refractive index of n surrounds the DC fiber.
  • Ring segment 18 also has a width 36 within the range of from about 0.7 ⁇ m to about 1.2 ⁇ m; more preferably of within the range of from about 0.86 ⁇ m to about 1.05 ⁇ m; and most preferably of within the range of from about 0.90 ⁇ m to about 1.00 ⁇ m.
